` 2,5 Claims. The present invention relates :to a harvesterconstruction.' More particularly, it relates to a tractor-mounted (compicker. i

In the case of tractor-mounted corn pickers, the principal diiiicultyencountered is with the attachment of the picker-to the tractor. Thepicker is normally large and heavy and should be positioned within thewheel line of the tractor. This Arequires that the picker extend overthe tractor axle and, consequently, itis diillcult to attach the pickerwithout obstruction oi.' the space around the tractor seat and therearaxle.

An object of the present invention is to provide an improved harvesterconstruction.

A further obiectis the provision of an improved tractor-mounted cornpicker.

Another object is to provide a irameworkior supporting an implement upona tractor.

tractor is a corn picker which comprises snapping units I5 positioned atopposite sides o1' the tractor body between the body and the tractionwheels I 4, husking means I8 extending transversely across the rear ofthe tractor, and a wagon elevator I'I extendingrearwardly from the rearof the: tractor. Each snapping unit I5 includes snapping rolls I8 and anelevator I9 arranged to receive corn ears from the snapping rolls I 8and to 4discharge them into chutes forming part of the huskiirg meansI6. As seen in Figure 6, the husking means I8, in

addition to the chute 20, includes opposed sets of tioned beneath thehusking rolls. Positionedx Still another object is the provision or asup- 1. porting framework forV a cord picker by which the',

A still further object is the provision of an improved corn Dicker. f

Still another object is the fan means i'or a corn picker.

Other objects will appear from the disclosure. According to the presentinvention a supporting framework for a corn picker is rigidly secured tothe rear xle of a tractor and extends rear- Wardly therefrom andtherebelow. Husking provision cfa novel corn picker is carried 'by therear axle of the means of the cornpicker is mounted atthe'rear of thetractor by'the supporting framework, and

l* snapping units are pivotally connected at opposite sides of thetractor to the husking means and the supporting framework.

The reference character III designates a tractor which comprises anarrow body jI I, a 'narrow front;

' truck I2, a rear axle I3,.and'rear traction wheels 'I4 spaced from thebody- III.- Mounted Vupon the snapping rolls 2l and husk conveyors 22posiover the husking means I8 is a fan means 23,

which includes a fan proper 24 and a fan housing 25 having outlets 28and 21 arranged to direct blasts o f air transversely of the tractortoward the elevators I9 and on the ears of corn' as they are dischargedfrom lthe elevators I9 into 'the chutes 20. The fan proper .24 ismounted upon a shaft 28 mounted in strips 29 secured to the -housin'g'25. The fan housing 25 is positioned within side plates or sheets39 ofthe husking means I5 and is secured thereto at one side by means ofbolts 3l, as shown in Figure 6, with a spacing plate `Sibetween thehousing 25 and the sidev sheet 30 of the husking means at that one sideas shown in Figure 2. The other side of the housing 25 Ais secured tothe side sheets 39| at that side by bolts 32a, as shown in Figure 2,with spacing plates 32h between the housing and thesplates 30. .Thebolts 32a also secure a tie-bar 32e to the sheets 39 at the one side ofthe housing 25. The huskingfmeans I8 also includes end plates 33 withopenings 34 therebeneath for the passage of husks fron?- the huskconveyors 22 and curved bottom t sheets 35. The huskingmeans is carriedat its i means ofa framework shown in detail in Figures outer ends onangular pieces 38 secured, as at 31, to the side sheets 39 and restingupon composite beams formed of angle irons 38 and channels 39 secured toone another. The husking means I8 is supported adiacent'its mid-sectionby means of brackets 40 securedto the side sheets 30 upon channels 4I.Thesey channelsl 4I also serve as a pivot mounting for the wagonelevator I1, as indicated at 42a in Figure 3. p d

The corn picker is mounted upon the tractor by f4 and 5. As seen inFigures 5 and 6, this framework includesvvertical angle members 42secured to the rear of the tractor axle I3. This securenecessary;V v

outer link 59 of each -pair of pins 46 and fit through slots, not shown,in the angle members 42. Nuts 41 hold the angle members 42 against thechannel 43. The slots and the pivotal mounting of the eye bolts 45enable the angle irons 42 and the supporting framework, of which theyare a part. quickly to be attached and detached. Flanges 48 at the topof the angle members 42 engage the top of the channels 43. Channels l49of triangular shape are secured to the angle members 42 and extendrearwardly therefrom and below the level of the rear axle I3. Atransverse tube 50 is secured as by welding to the rear ends of thechannels 49 and extends beyond the channels 49 and in spaced parallelrelation to the rear axle |3 well to the rear of and below the same.Longitudinal members in the form o1' channels are secured as by weldingto the ends of the transverse tube 50 and extend forwardly therefrombelow the rear axle I3 to a point somewhat forward of the axle.Extension pieces 52 are secured as by welding to the lower ends of theangle members 42 and extend forwardly therefrom below the tractor axleI3 at about the level of the forward ends of the longitudinal members5I. Secured to the extension pieces 52 and the forward ends of thelongitudinal members 5| are brackets 53. Extending between beyond theends of the tubular spacer 56 between the tube 51 and the sleeve 55 andpermit relative rotary movement between the tube 51 and the bolt 54.Secured at theends of each tube 51 are links 59 in the form of channels.Through the end of each pair of linlm 59 dextends a. bolt 60 having nuts6I thereon which prevent endwise movement of the bolts 60 with respectto the links 59. A sleeve 62 is positioned on each bolt 69 with a spacer63 therebetweenv and is rotatably mounted upon the bolt 60 by means ofbearings 64 positioned beyondthe ends of the spacer 63. Washers 65 arepositioned between the bearings 64 and the links 59 so-as to keep thebearings 64 I in place. Secured to the ends of each sleeve 62 is a wide,shallow channelv member 66 opening at the top, and a bent channel member61 opening Thus, there are two counterbalancing springs 15, one for eachsnapping unit 5, and they act by means 0f the triangular pieces 13 onthe outer links 59 and the links 66 and 61 to exert a lifting force. atmid-points of the snapping units I5. Each outer link 59 with itstriangular piece attached thereto may be considered to constitute abellcrank through which a counterbalancing force is applied.,

Secured to each inner link 59 is a downwardly projecting triangularpiece 18 which is resiliently connected, by means of a bolt 19 and aspring 80, to a link 8|. The link 8| at the right-hand side of the frameas viewed in Figure 4 is connected by a hook 82 to an arm 83 secured tothe end of a lifting shaft 84. As shown in Figure 5, the lefthand link8| is connected by means of a hook 82 to a lifting lever 85 secured tothe end of lifting shaft 84. The lifting lever 85 has detent mechanism86 engaging an arcuate toothed m'ember 81 secured to an angle iron 42and a channel member 49 by pieces 88 and 89, respectively. Raising ofthe snapping units I5 about their pivots on the husking means I6 aboutthe pins 12 is effected by a clockwise movement of the lifting lever 85which, acting through the links 8| and the shaft 84, produces aclockwise movement of the links 59.

As is tobe seen in Figure 3, the husking means |6 is positionedimmediately to the rear of the transverse tube 56. The husking means iscarried on the tube 58 through pieces 96 secured thereto, as bysoldering or welding, and bolted, as indicated at 9| to the beams formedof the angle members 38 and the channels 39. The channels 4I, which havebeen previously described as supporting the mid-section of the huskingmeans |6,

'are also secured as by soldering or welding to the transverse member50.

toward the side, as viewed in Fig-ure 4. The ends of the links 66 and 61have openings 68 and 69, respectively, for the reception of a bolt 18 byvmeans of which the links 66 and 61 are pivotally J rear end to ears 1I,only one of which is shown as in Figure 3, by means of pins 12, only onebeing shown as in Figure 3i Thus, each snapping unit I5 is enabled topivot about an axis on the husking means I6 well above and to the rearof the rear axle I3 as determined by the pin 12.- Thus,

the connection of the mid-point of each snapping unit I5 with thesupporting framework by means of -the links 59 and the links 66 and -61lis Secured to the links 59,/to a triangular piece 13, as seen in Figure3. JAY-bent member `141s connected to each triangular piece 13 and, inturn, to a counterbalancing spring 15 connected to a bolt, 16 connectedFrom the foregoing description it will be evident that a new and novelcorn picker. construction has |been provided. The construction is novelin that it includes the 4mounting of the corn picker .upon a frameworkwhich is secured to and extends beneathgthe rea;` axle of the tractorupon which the corn picker is mounted. The framework rigidly\carries thehusking means of the corn picker and also movably carries the snappingunits of the corn picker by connections which include pivotal 'mountingof the rear ends of the lsnapping units upon the husking units andmovthe snapping units. upon the husking units is novel, and this noveltyalso includes the positionin'g of the pivotal mountings above and to therear of the rear axle of the tractor carrying the corn picker. Anotherfeature of novelty is the provision of the fan means 23 over the huskingmeans I6 in such a way that it directs blasts of air outwardly towardthe rear ends of the snapping units across the ears of corn as th'ey aredischarged from the snapping units into the husking units.

With reference again to the framework forsupporting the cornpicker uponthe tractor and the mounting of the snapping units with connections to,thehuskingmeans and the framework, it will be seen that a relativelyeasy attachment and detachment of the corn picker is provided. This isnot illustrated, but it can be readily understood by reference to Figure3. When the picker is to be detached, rst-of all `the mid-points of thepicker are detached from the frameworkby remaval of the bolts 86, the"links 61 and 66 remaining with the'snapping units I 5 and the links5,9, with the supporting framework. Then-supporting legs, not shown, maybe dropped from the snapping units to the ground approximately at thepoint of the links 66 and 61,4 and the pins 12 are removed. 'Ihen thetractor with the huskig means I6, with the 'supporting framework stillattached thereto, is backed away from the snapping units I5. Then, legs,not shown, are dropped from the supporting framework to the ground sothat the weight of the framework and the husking means is carriedthereon, and the framework is detached from the tractor axle I3 by quickremoval of the eye bolts 45 from the slots of the angle irons 42, aspreviously described.. For attachment of the corn picker to the tractor,the supporting framework and the husking means I6 are first attached tothe rear axle, and then the tractor with the vsupporting framework andthe husking means in place', are driven into position with respect tothe snapping units l5, so that the snapping units may be reconnected tothe husking means by replacement of the bolts 12 and the links 59 may bereconnected with the links 66and 61. There are two reasons why this easydetachment and attachment of the corn picker are possible. The first islthe supporting framework for i the com picker, which is secured tothetractor rear axle and extends below it. The second is the pivotalmounting of the snapping unit I5 on t-he husking means I6 on pivot axesdetermined by the pins 12, which are to the tractor rear axle.

Brief reference will now be made to the means by which the variousoperating parts of rthe corn l'picker are driven. As seen in Figure 2, apower take-off shaft 92 extends rearwardly from the rear of the tractorI0 to the husk-ing means Il. One

sprocket chain 93 is drivenby the power take-- oi shaft 92 and, assli'own in Figure 6, drives a sprocket 94 transmitting drive to thesnapping rolls I8 in a manner not'shown, a sprocket 95 and an idler 96.'I'he sprocket 95 drives a shaft 91,

driving a bevel gear 9B, in `turn driving a second bevel gear 99 drivingone set of husking rolls 20. A shaft 91 also drives a sprocket |00,which drives a chain |0I,.driVing a sprocket |02 for a shaft |03 for abeater, not shown, and a sprocket |04, driving a shaft |05, driving aysprocket |06 for the husking conveyer 22. Therel is also an idlersprocket |01 meshing with the chain |0I and `serving to keep the .chainI 0| wrapped in driving engagement with the sprockets |00 and |04.. Alsodriven by the power take-pff shaft 92 is a chain |08, which drivesvarious parts in the same way as sprocket chain 93 drives them. However,this chain |08 engages an additional idler sprocket |09 and a sprocketI0, driving a shaft III, driving in turn apulley I2, driving a belt I3,driving a pulley |I|` on the fan shaft 28.

The intentionl is to limit the invention only within the scope of theappended claims.
